Genetic diversity and SNP's from the chloroplast coding regions of virus-infected cassava.

Cassava is a staple food crop in sub-Saharan Africa; it is a rich source of carbohydrates and proteins which currently supports livelihoods of more than 800 million people worldwide. However, its continued production is at stake due to vector-transmitted diseases such as Cassava mosaic disease and Cassava brown streak disease. Currently, the management and control of viral diseases in cassava relies mainly on virus-resistant cultivars of cassava.

First report of Cassava brown streak viruses on wild plant species in Mozambique.

Cassava brown streak disease (CBSD) caused by (CBSV) and (UCBSV) is the main constraint to cassava ( Crantz) production in Mozambique. Using RT-PCR to amplify partial coat protein nucleotide sequences, we detected for the first time the occurrence of CBSV in two non-cassava perennial wild plant species: () Exell. and (Burm.
